摘要:重新研究了济源四足动物群的材料,表明其以锯齿龙类的复齿河南龙为主体,还包括至少三种迟滞鳄类和一种犬齿兽,可能还有一种凶脸兽。根据甲片特征推测,迟滞鳄类至少包括中国毕氏螈 Bystrowiana sinica, 扁平济源盖螈(新属新种) Jiyuanitectum flatum gen.et sp. nov.以及大型脊廊盖螈(新种) Dromotectum largum sp. nov.。根据四足动物组合,济源动物群大致可以与俄罗斯Sokolki组合带的Ilinskoe亚带以及南非的小头兽组合带对比。

Abstract Reexamination of the specimens from the Jiyuan tetrapod fauna, shows that this assemblage is dominated by the pareiasaur Honania complicidentata and comprises three chroniosuchian species including Bystrowiana sinica, Jiyuanitectum flatum gen. et sp. nov., and Dromotectum largum sp. nov., one cynodont species and possibly one gorgonopsian. It is roughly correlated to the Ilinskoe Subassemblage of the Sokolki Assemblage of Russia and the Cistecephalus Assemblage Zone of South Africa.
